Dandelions are a perennial broadleaf weeds that are a problem for numerous homeowners around Northern America and beyond. Since they are a perennial, they will reemerge each year if not killed off. Dandelions will be most noticeable in the spring when they bloom their infamous yellow flower heads.
It is important to take on a dandelion problem quickly and efficiently to avoid any issues with the weeds spreading. We recommend to spot spray them instead of putting down a blanket of weed killer such as a weed and feed fertilizer. Spot spraying will typically be much more economical and environmentally-friendly.
